Ads may be Animated and have embedded sound. Almost anything can be done as long as the size restrictions are adhered to. Button ads are less descriptive and load very quickly. They are by far the one of the most economical in terms of per click or per impression ad cost with limited
Visual Impact. Generally, as a media buyer you might want to mix it up a little.

Button ads are an effective tool in that they tend to load first and can be at the top of the Page next to a site Logo. Some publishers will mix them in with the text. They are displayed as a fixed width and height Horizontal image usually centered in a cell or on the page. The Banner ad can contain animations using Flash or an animated gif image. The ad is image linked and the user is taken to a new or the same Window when the Button Ad is clicked. This can either leave your site visible and the user sticks around or load site in the same window. It is a
versatile and an adaptable medium.
